When I visit certain pages with ties to Google Ads or Google Trends, such as yellowpages.com or knowyourmeme.com, I get an immediate redirect to a blank Google page, usually google.com/uds... along with some term like adtest and the desired URL in html/unicode text.

This only started a few weeks ago after I upgraded to Firefox 19.0 and upgraded my Java, Flash and other plugins to the latest versions (straight from the official websites; no chance of fake third-party upgrades). I just upgraded to the FF20 beta; the issue persists here as well. I also tried disabling my ad blocker (GlimmerBlocker; a standalone proxy-based blocker) to no avail.

I'm not sure if it's a Javascript issue with Firefox, or if Google changed their code, or what. I didn't have this problem on Firefox on Windows on a school computer, although I don't recall if that was a current or older version.

Try the Firefox Safe Mode to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

You can open the Firefox 4.0+ Safe Mode by holding the Shift key when you use the Firefox desktop or Start menu shortcut.

Or use the Help menu item and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Don't select anything right now, just use "'Start in Safe Mode"To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.If it is good in the Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.
